Hutchinson tyre sensor

Hutchinson’s 12g sensor hooks over your valve stem and sits inside your tyre, where it monitors air and sealant levels, and can even recommend pressures based on your set-up/riding preferences. This is all done via a dedicated app, which connects using ANT+ or Bluetooth. Accelerometers mean it can log lean angle and wheel speed too, with scope for it to suggest use of a different tyre. www.windwave.co.uk
